| Title of the article | Features of clay soil deformation under three-axis block mode cyclic loading, taking into account the formation of micro- and macrocracks |
| Abstract. | Problem statement. The main purpose of the research is to study the parameters of strength and deformation of clay soil under triaxial compression, under block mode cyclic loads. To date, there are no data on the results of studies under the specified loading mode. Results. Experimental studies of the strength and deformability of clay soils with three-axis compression ?1??2=?3 under block mode cyclic loads were carried out. A distinctive feature of experimental studies is that they are carried out in three-axis prismatic compression devices with an aspect ratio of 100?100?200 mm. The regularities of changes in the main characteristics of the soil during transitions to blocks with high and low stress levels are established. New data on the regularities of clay soil deformation under stationary conditions of repeated cyclic loading were obtained. Conclusions. The significance of the results obtained for the construction industry consists in the study of vibration creep deformations and changes in fatigue resistance to the destruction of clay soils under three-axis regime block cyclic loading. It is found that the stress-strain state, deformations and fatigue strength of soils change depending on the sequence of alternating blocks with different values of the maximum load of the cycle. Keywords: block-cyclic loading, stationary and non-stationary loading, vibration creep, clay soil, nonlinear deformations of soil vibration creep. |
